Looking to replace my totaled XB12Ss. I'm really wanting the 1125R because I want the best Buell has to offer but I love the character of the Harley engine. However, top speed is not my main concern, acceleration and the ability to do power (clutchless) wheelies as well as cornering abilities is. Does anyone out there have experience with both bikes? Would the XB12R with an XB9 primary gear be more of a wheelie machine? Any other insight into the differences between the 2 bikes would also be greatly appreciated. Thanks in advance.

I have owned an XB12S, XB12R and an 1125R.

The 1125R blows both the lightning and firebolt out of the water in pretty much every department. Same torque numbers and 50 more ponies....

The XB9r and XB12r have a 2-inch shorter wheelbase and (with the 12) more torque. That should mean easier wheelies.

For a stunt bike, it strikes me as though the XB might be better, at least on paper.

But, I'm no stunter. And, I agree with Edm... the 1125r is a much better overall bike.

Isn't the peak torque on the 12 at a lower RPM than that of the 1125R. I know gearing will relate to how much torque is applied to the rear tire so that's why I'm inquiring as to the XB9 primary gear.

Darcy, since you've owned 2 12's and an 1125, does the 1125 power wheelie easier the the 12?

Ive owned xb12r and traded in for my 1125 and i find the 1125 is better in every dept except gas mileage which might change after new 09 map. one thing i miss about my xb12r is the low rpm driveability, its better in stop and go traffic and less shifting.

Bjorn, thanks for the input. I realize it's tough to beat the mpg of the XB's, although if I put in the XB9 primary I'm sure that will drop by a little. But it's looking like the 1125 is probably the way to go for me. I really haven't heard of anyone the regretted the switch from Harley to Helicon.

Wait and try out an 1125CR, they are geared a little lower than the 1125R.

That one should be a wheelie machine where ever you live.
At my altitude(5000+ ft), Loretta's front wheel stays on the ground pretty easy.

If you're looking to conserve the wear on your front tire by keeping it in the air, the 1125CR will be your ticket. Read up on the specs, and look at the wide bar kit. This is the config I'm going with. I'm not much of a wheelie addict, but that will happen to be a by-product...

I am curious to find out if the gear change in the CR is more the enough to offset the longer swingarm. But what I haven't figured out yet is how it has a longer swingarm but the wheelbase is the same. Anybody know. Either way I'm not sure I can get 100% behind the CR. Looks decent from most angle except standing by the back tire a couple of feet away, those pods just stick out too far w/o having a fairing to somewhat blend into. Also the bend on the mirrors/signals is all wrong. Just my $.02. I will definitely test ride one when I get a chance.

I'm curious if 1125R owners would be able to buy parts to easily apply the CR lower gearing.

In other words is it just a sprocket(s) / belt change and if so, does any one have the part numbers?

It's probably two sprockets and a belt to make the change.

Keep in mind it will knock your speedometer (and mileage clock) off accurate.

I've got an Ss and an 1125 as well as several tubers. Definately go for the 1125, it must be easiest bike on the planet to wheelie
I'd be very cautious of lowering the primary gearing on any XB (including the later, vastly superior, sliding dog gearboxes) since you'll be increasing the torque through a gearbox that doesn't have a reputation as being robust and doesn't have a trapdoor for easy and cheap repair. In fact, I know of some XB's that that have been uneconomic to repair when the boxes have gone t/u.
Buy a late tuber, the best Buell made to date

The swingarm is attached to the bike further forward than on the XB. The swingarm attaches directly to the engine.

You need the CR swingarm as well.

I have to admit I am partial to the S1 (the sexiest hooligan bike on the planet) but I have never ridden a tuber and I understand the XB handle much better, is this true?

The S1W is THE Buell but a X1 handles better. The XB range are bit 'nippier' in the bends but don't have the style of a tuber or the power of a 1125. My wife rides mine

+1. The swingarm is a tad longer for the CR, which keeps the geometry correct for the new rear pulley and belt.

I was pretty sure the CR had a longer swingarm than the R but in the specs on Buells website they have the same wheelbase. Did the change front geometry to make up the difference or is it a typo?

The CR swingarm is only about 0.1 inches longer, just a tweak to keep the belt tension right with different gearing. So it doesn't show up in the overall wheelbase worth noticing.

Open mouth, insert foot.
I did my last post thinking the question was as compared to the XB, not the 25r vs. cr.

Damn, wrong on both counts, not a front geometry change or a typo. Thanks anon, I had only heard that the swingarm was longer but never how much.

I have owned a 9S, a 12R and the 1125R.

The 1125R will power wheelie WAY better then the other two. In second gear you can whack the throttle with a small tug on the bars and ride a wheelie as far as you can/want to.

By the way, I did a track day yesterday and got a ton of compliments on the looks of the bike. Then, after a couple sessions, people kept coming up to me telling me how they cannot believe how hard I pulled away on them exiting corners.

I like my bike.
